Create a punnett square to illustrate the probability of a black rabbit if a white male were mated with a black female. use w for white, which is dominant, and b for black, which is recessive (hint: create a punnett square for a homozygous white male and a heterozygous white male).

0%

Explanation:

Allele for white colour is represeted by w.

Allele for black colour is represented by b.

b allele is recessive to w allele.

Homozygous white rabbit will have the genotype ww.

Heterozygous white rabbit will have the genotype wb.

Crossing ww and wb:

ww  x   wb  = ww, wb, ww, and wb

Since w is dominant over b, it means all of the offspring are white with 50% being homozygous and 50% being heterozygous.

The probability of a black rabbit offspring is 0%.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
